Would you recommend Dr.Betz? In this Forum are many different opinions of him... .
I do recommend him for femurs, especially because you will be doing just 6cm. I had a great result with him, I can't really complain. It really changed my life for the better. And I did recover my athletic ability post-surgery even with an extreme amount of lengthening, so Betz did something right.
He used to say that I had "perfect compliance" (I really followed his instructions to the letter) which is not usual for male patients.
Having said that, the last centimeter were really painful. It is not a walk in the park.
I had the luck of having a lot of other LL patients with me at Park Hotel, so that made the whole situation better and actually fun.
I'm a little nostalgic about it. It was like a crazy college dorm with people on crutches...
He said years before he used a nail, made of another metal. But I don’t really can imagine to go back to work 2 weeks after surgery. You are talking about 2 months after lengthening. So how many months your were not going to work ?
I can work from home and I usually work by projects (not a 9-to-5 job), so I had a little bit more flexibility than you, as I didn't have to come back to a daily job. It took me 4 months of lengthening and I could not work AT ALL. The pain and lack of concentration power (due to the painkillers and overall pain) made impossible to work in a professional level.
I only went back working 3 months after lengthening. I used those 3 months pos-lengthening to concentrate on my physiotherapy. I think it really paid off and my recovery was much better because of it.
But again, I did 9cm/10cm and with the old nail. I think your recovery will be much faster with 6cm and the new nail. But you should plan to not work during lengthening and at least 2 (maybe more) months later if you can (I know that's not possible for everyone).
